@msales: "Hello,
I am using the the OpenSSL enc command to encrypt and decrypt a test file.
When using AES-GCM mode, I can encrypt but cannot decrypt the result.
Even though I succeed with all other modes.
Example is as follow :
openssl enc -e -a -aes-128-gcm -nosalt -p -K 
28C65581AABBBA0EBFC1DB5D5C614FEA -iv D2D136CA54FEB7C48C9E4358 -in 
test.dat -out enc.txt
openssl enc -d -a -aes-128-gcm -nosalt -p -K 
28C65581AABBBA0EBFC1DB5D5C614FEA -iv D2D136CA54FEB7C48C9E4358 -in enc.txt
Get a  : 'bad decrypt' output
Test file contains "bla bla bla bla bla bla bla bla bla'.
Using OpenSSL 1.0.1c downloaded from source code, and compiled under 
Windows 7.
Also, if text file contains shorter data (< 16 bytes), I cannot encrypt 
in AES-XTS mode.
(no output)
Did I miss something ?
Thanks in advance.

Well technically those modes need special handling which wont necessarily work
with the 'enc' hoovermonica@example.net.
